sf::Text bounds not updated
« on: May 31, 2012, 12:35:35 am »
Okay, I have a little problem with sf::Text that I need some help with, or some clarification.

Basically this happens:
sf::Text text;
std::cout << text.getGlobalBounds().width << std::endl; // 0
text.setString("");
std::cout << text.getGlobalBounds().width << std::endl; // 0
text.setString("a");
std::cout << text.getGlobalBounds().width << std::endl; // 16
text.setString("");
std::cout << text.getGlobalBounds().width << std::endl; //16

In words: Once sf::Text had some sort of string and is set to an empty string it still keeps the bounds of the previous one.

Now I'd like to know if this is intended, if I'm doing something wrong or if this shouldn't be that way. Is there maybe a better way to clear the string?

[edit]
Oh yes, I'm using 2.0 RC.

There will be a reimplementation of the getGlobalBounds() function, see issue #216

Ah, I didn't see that. It behaves strangely indeed, but this thing I couldn't find a workaround for.

Anyway, thank you for pointing me there.

Take a look at the links in the GitHub issue, in a forum thread I proposed a solution.

I will do that, but I have found a solution already. It's not the most elegant, but all I have to do is remind myself of it when this will be fixed/updated.

The problem I had was with the text-input of my gui-system. Whenever the last character got removed the cursor would stay on a wrong position. Now, whenever the string is empty it gets set to the relative position of the control, and not the sf::text bounds anymore.
